This sample was collected from the pink robe of the kneeling woman in the lower right corner before the complete removal of the discolored overpaint. The red-brown ground can be seen as well as three layers of paint; the light yellow paint may be the underlying flesh paint of the woman's back while the uppermost pink paint corresponds to the drapery (visible light/ultraviolet illumination/100x magnification). Red lake colorants were occasionally extracted from dyed textiles which may explain the presence of the curious shaped particle in the pink-colored paint layer. Ultraviolet illumination helped to reveal the presence of a double red-brown ground; the lack of strong auto-fluorescence in the uppermost layer also supported later findings that confirmed that this layer was unoriginal overpaint.

This sample was collected from a white-blue highlight on Abner's helmet after the removal of the degraded surface coating. The red-brown ground can be seen followed by several layers of paint, indicating that multiple adjustments were made to this area of the composition (visible light/ultraviolet light/100x magnification). Ultraviolet illumination helped to reveal the presence of a double red-brown ground as well as several colored layers of paint beneath the light-colored highlights. These yellow and red colored layers may correspond to initial position of Abner's head and helmet as later examination with x-radiography confirmed that major changes were made to this area during the final painting stages.

This sample was collected from the green-colored mountains in the distant background after removal of the overpaint and degraded surface coating. The red-brown ground can be seen followed by a thin layer of green paint rich in yellow/green earth and lead white (visible light/ultraviolet light/100x magnification). Ultraviolet illumination helped to reveal the presence of a double red-brown ground.

This sample was collected from the green-colored leaf from the flower garland after removal of the overpaint and degraded surface coating. The red-brown ground can be seen followed by a thin layer of green paint rich in yellow/green earth and lead white with a trace of vermillion from the edge of the red flower (visible light/ultraviolet light/100x magnification). Ultraviolet illumination helped to reveal the presence of a double red-brown ground as well as a curious auto-fluorescent glaze layer between the paint and ground layers. This layer may correspond to a pigmented glaze/varnish layer that was applied to this area before the artist(s) began the painting process.

This sample was collected from the green-colored cushion on King Saul's throne before removal of the degraded surface coating. The red-brown ground can be seen followed by a two thin layers of paint (visible light/ultraviolet light/100x magnification). Ultraviolet illumination helped to reveal the presence of a double red-brown ground, green earth particles in the paint layers, and the thick nature of the degraded surface coating in this particular section of the painting.
